CHARLES TRUESDALE, OF CINCINNATI, OHIO, ASSIGNOR TO HIMSELF AND WILLIAM RESOR & CO., OF SAME PLACE.

Letters Patnt No.`96,743, dated November 9, 1869.

STOVE-G-RATE.

The Schedule referred to in these Letters Patent and making part of the same ments on 'the class'of shaking and dunping-grates,

described in ny patent of July 20, 1869; and

My said improvemcnts cousist in First, a certain form and arrangement of the front and bottom bars, which, while allowing the necessary agitation of the lat-ter, for separation of the ashes,

preserve a practical eoutinuity of said bars, so as to prevent the escape of cinders, and the clogging of" the bars thereby.

Second, a devie, by which the grate-bottom is, in ordinary use, restricted to such agitation as is sufiicient to separate audprecipitate the ashes, but which, on removal of a pawl, enables the said bottom to be swung to a vertical position, so as to empty or dump the grate;

Third, a peculiarly-formed detaehable lever or handle to the shakingbottom, said handle also serving :isa lifter for the stove-covers, hearth, &0.

Eigure l represents, by rear perspective View, a cook-Steve fire-place, embodying my improvements, a portion of the fire-back being broken away. i

Figure 2 is a side elevatiou of such fire-place, with portions of the janb removed, and with the gratehottom in its normal or horizontal position, the rockshaft being in section.

Fignre 3 is a similar elevation, with the grate-bottom tilted, for preeipitation of the ashes.

Figure 4 is a similar elevation, with the grate-bottom brought to the dumping-position.

Figure 5 is a longitudinal section of the Operatingend of the grate-bottom rock-shaft.

Figure G is a perspective View of the same, the han-' dle-being detached.

A A' represent the side plates or jambs; B, the front plate; and O, the back plate of the eook-stove tireplace.

The front potion of the grate consists of a series of bars, D, which depend perpendicnlarly from a horizontal bar, 1)'.

For a grate-front of considerable height, a crossbar, (Z, may be added.

The lower cxtremities of the bars D are unconnected.

The bottom bars E are in the same vertical planes with the front bars, and are cast solidly, or otherwise li-nly attached to rock-shaft F, whose ends are jourial'led horizontally in the jambs A A'.

The rock-shaft F is arranged slig'htly in the rear of the mili-distance from front 'to back of the grate bottom, in order that said bottom may, when undistnrhed, 'rest firnly in a horizont-al position upon one or more lugs, Gr, projecting interiorly from the stoveside or front;

One extrcmity of the rock-shaft F projects outside of its supporting-jemi), andhas' a flattened portion, H, teriniiatingin'an uptnrued lip, I, to enter the correspondinglyshaped eye j, of a' landle or lever, J, whose other end has a hook, j', adapted for use as a lifter for the cover-s, hearth-plate, and other loose plates of` the store.

In order to enable. the handle J to be used at will,

for either of the purposes designated, it is readily dei tac'hable from the shaft F.

\Vhen not needed on the shai't, the eye j enables the handle J -to be suspended from a nail or ho'ok, if desired. e

The portion of the rock-shaft F outside the plate has also a nick, f, to receive the point of a pawl, K, which nick and pawl serve. to restrict the rocking action or shake of the grate-bottom to that shown in fig. 3, in ordinary use.

When it is dcsired to empty thegrate, the pawl K is lifted, andthe grate-bottom is, by means of the lever J, tilted to the position shown in fig. 4.

. A stad, L, projecting from the jamb, may limit the backward movement of the pawl K.

In order to prevent any* escape or lodgement of oinders between the ends of the bars E and front bars or back, during the shaking merely of the gratebottom, I give the lowest portion of the inner edges i of the pendcnt bars "D,-,and the portion of the fireback, opposite the rear ends of the bars E, the forn of coneaves d" and c, concentric with the axis of vibration. e

The front and bottom bars D and E, being *in common planes, may be of the ordinary distance apart, and oppose no unusual obstacle to the stirrer orpoker.

I claimfas myinvention- 1. In the described oombination with the shakinggrate E, the concavities d", on the front bars, for the purpose set forth. A

2; The described combination of shakinggrate E and concavities d" and' c.

3. The devices fand K, or their equivalents, for restricting the oscillation of a shaking or dumpiuggrate, snbstantially as set forth.

4. A grate-bottom, adapted to be tilted in the planes of its bars, and about an axis parallel with the grate front, said bars being unconnected at their front extremities, and having coutiguous thereto, and in the same planes, a series of pendent front bars, whose lower extrenities are likewise disconneeted froni each other.

5. In coinbination, or for use with a tilting gratebottom, the convertible handle and lifter J jj'.

In testinony of which invention, l hereunto set my hand. i
